Identify the biases they bring to the table and understand how they can be used (for good or bad)?

Listen to and respect all views while recognising ideas are not equal?

Bring others along but not at the cost of sound decision-making, even when that means standing alone?

Encourage a style of dissent that does not veer to chaos or produce fake consent?

Coherence is so strongly associated with survival and its value so deeply embedded in management practice that we would rather deal with the future consequences of a bad decision than the discomfort of going against the group here and now.

Groupthink has been implicated in many disasters, from the Bay of Pigs to the GFC. What has emerged in much of the research that follows these events is that many people had doubts about what was happening but did not speak out, sometimes to remain ‘in’ but also because of an understandable concern they might lose their jobs.

We’re told that jealousy is bad and we should rise above it so people deny or suppress the feeling.

The problem? They are still jealous but now feel guilty and ashamed too and are no closer to understanding why the jealousy emerged or what they can do to manage the discomfort.

But if you really want to know what you value, then jealousy is a merciless guide.

Nothing cuts through the theoretical idea of what you think you value to what you actually value faster. Learning to read it is invaluable.

For example, tell me about a runner who broke the world record for the 100 meters and while I am glad for them I am otherwise unmoved. The same can be said for the Oscar winners, Grand Prix drivers, math geniuses, amazing business people or International Most Fabulous Persons Of All Time.

But mention a 20-year old novelist who has managed to shortcut the tortuous path to publishing and create an immediate best seller and that gets the heart pumping.

Why? Because my path to publishing has been long and at times tortuous. Apart from the published works I have 11 unpublished novels, umpteen plays and short stories in the drawer (of my Mac that is).
